I do understand there is agent.id or circuit.id but those come from the access side and not something I can use. I do also realize I can look for the Interface slot/module/port/vlan but when you’re dealing with hundreds of interfaces, I’d rather define a constant and just tag the interfaces under a specific name/group and send that to the RADIUS server.

Either "radius attribute nas-port-type" to override NAS-Port-Type on the
interface, or maintain an interface->group mapping on the RADIUS server
side for use with NAS-Port. You'll need to preprocess the request to get
a usable string in either case.
